How to set custom refresh rate w/o using a program like Powerstrip

[Rain Man]

I remember editing the registry to implement custom refresh rates, but I have since reinstalled Windows, and I forgot which keys to edit.

Depending on your video card, you may be able to set the refresh rate in the Control Panel / Display / Settings / Advanced / Adapter.

Is this what you're looking for?

HKEY_LOCAL_MACHINE\System\CurrentControlSet\Services\Class\Display

You can also edit your video card driver's .inf file with custom settings. Once you reinstall the drivers using that .inf file, the custom settings will take effect.

hztool works great.
